Installation
Electrical Installation – Main Power and Trigger Signal Wiring
All installations must be in accordance with city, county, parish, state or provincial electrical codes and
should be performed by a certified electrician. A ½” nonmetallic conduit system must be used to install the
power cord. For questions, please contact local licensed electrical contractor.
Caution: Before electrical installation is started all electrical power must be turned off to any trigger device or
controller at the appropriate service panel. Lockout and tag out procedures must be used. There is a potential
for exposure to high voltage conditions when the Dairy Clean enclosure is opened.
A complete survey of the site installation should be completed in advance of starting the Dairy Clean installation.
1. The Dairy Clean is prewired with a power cord that includes a 115VAC grounded plug. Simply plug the
power cord in grounded 115VAC wall outlet for main power.
a. Wall plug/socket adapters may be used to plug the power cord into various country plug
configurations. The adapter must be rated to accept 115/230VAC 10A.
b. Alternative Main Power Hardwire– The molded plug can be cut off and connected directly to an
alternate power source. The operating voltage 100-250VAC 50/60HZ. The system will automatically
adjust to the incoming voltage. Machine ratings and instructions must be observed. Consult with
equipment manufacturer for connection information.
2. Select a location to mount the Dairy Clean on a wall that will allow access to the chemical product containers
and the chemical product feeds points on the machine. Direct spray or high steam areas must be avoided.
3. If using the 951 series flush manifold or any other flush manifold , select a location that will allow all the
electrical (power for solenoid valve and/or pressure switch) and tubing connections to be accessible. It should
be noted that the flush output on the electronic control board is a 24VDC signal. The solenoid coil for the
flush valve will need to match this output signal.
Trigger Signal Wiring
It is possible to cutout supply signals from the machine that fall below 70VAC by using the voltage cutout switch.
When the Dairy Clean enclosure is opened the voltage cutout switch can be accessed.
• When this switch is set to the 12V-100V setting the system can accept supply signals from the machine
that range from 12-250VAC. This is the factory default setting for any product.
• When this switch is set to 100V-240V, the system can accept signals that range from approximately 70-
250VAC.
Note: When combining 2 or more trigger signal inputs from one supply signal from a controller, it is
recommended to have the voltage cutout switches set to 12V-100V settings. The system will accept 12-
250VAC trigger signals.
See the wiring configuration table on the next page for definition of the various wires.
